Application filed MarchlS, 1914. SeriaLNo. 825,667,.

To all whom it may concern:

I Be it known that I, Mai-H lts Bonn, a citizen of the United; States, residing at Stic'kney, in the county of Aurora, State of of the invention, such as. willenable others skilled inthe art to which k d it appertailis to This invention relates to certain novel and useful improvements in locking devices, and while I have in the present instance shown and described my inventidn as employed in connection with what is commonly known as a buckling end gate, I wish it to be understood that the invention is not limited in its useful application to this particular purpose, as itis equally well adapted for use in connection with barn doors, the side walls of wagon bodies, boxes and similar structures. I p

In carrying out my invention it is my purpose to provide a locking device by means 'of which the gate, door or other structure may be firmly and securely fastened so that the liability of its being accidentally opened is obviated;

Furthermore, it is my purpose to provide. a locking device of this character which will embody in constructionthe desired features of simplicity, efiiciency and reliability, and which may be manufactured and marketed at a relatively low cost.

In the accompanying drawings: lji'gure 1 is a view of a portion of a wagon box having an end board applied thereto, and showing my lock as employed in connection there" with: 'Fig. 2 is aplan View of the 'part shown in Fig. 1. Fig. 3 is a cross sectional View taken on the line 8'3 of Fig. 2, the portion of thelock board 5 beingbmitted Fig. 4 is'a Similar or unlocked positionf Fig.5 is a view 05a modified form of lock adapted tobe employed in connection with a barn door hr the like, certain of the parts of the lock being omitted. Fig. 6 is a plan view or the keeper bar which is attached to the inside wall of the end gate. Fig. isa 'detail' View "of'a portion of the locking spindle.

Referring now to the accompanying drawings in detail, the letter A designates, in the present instance, the rear portion of the wagon box provided with the ordinary vertical retaining cleats 1. The end gate is indicated as an entirety by the letter G and includes the relatively long section 2 and the relatively short section 3, the two sections being connected by means of the hinges 4:, so that'the gate m y'buckle outward. The shorterend: gate section has rigidly connected thereto a lock board 5 which is tapered or reduced atone end as at 6, this tapered endhaving an open inou thed slot 7 for the purpose hereinafter described.

The lockin'gde'vice proper is mounted upon the relatively long section 2 of the tail'boar'dand embraces a sleeve 8 seated in the bore 9 eirtendingthrough the board, this sleeve 8 havin'g'a flange 10 at one end hearing against one side ofthe bloard anda collarll which bears'ag'ainst the opposite side ofthe board.

The numeral 12 indicates, a post having a reduced threaded shank 13 which is screwed intothe threaded bore-140i the sleeve 8, a shoulder 15 being formed between the outer end'of'th e threaded shank of the post and the body ofsuch post, this i shoulder bearing against the flange'IO which'is at the outer face of the tailgate section 2. This post 12 which adapted to be rotated or turned is provided with a horizontal bore 16 extending therethrougl from end to end, the outer endef thebore terminating in an enlargement or recess 17 which 1 is formed in the elongated or rectangular head 18 of the post, this el d'ngated head forming the lock ingfbar oftheidevicefas will be hereinafter understood. I i

liliztending through the bore 16 of the post 12 is i$PiIidle 19,"u1e uer end of which terminates-in a transverse, bar-like head 20 having'the handle"21 cast therewith. Carried by the spindle below the head are the flanges 2 2'22"which" seat in the recess 17 formed in the head 18 055 the post 12. As will be noted, thes pindle 19 extends entirely' through the bore16 of the post 12, and eonseque'ntlyits innerend projects beyond the inner 'face ofthe tail board section2 and'al'so extends through the'bore23 ofthe spring '24 which 'i's in the form of a bowed metallic strap which bears against grooved and cut to constitute a casing for the inner-face of the board section 2. A

.wearingplate is carried by this spring strap. 21 and is also formed with a central bore alining with the bore in the strap. The terminal of the shank 19 carries a reetangular locking block 26. The numeral 27 indicatesa vertical bar or block which is fastened over the strap spring and over parts of the lockwhich lie at the inner face of the board section 2,. this block being within the recess 30 and form a floor therefor, this plate 32 having a rectangular central opening 33 of the same size as'the recess 31 and registering therewith. It will be noted that the slot or opening 33 in the plate is of sufficient size to accommodatethe'rectangular locking plate 26 and permit the latter to lie or seat within the recess 31 at de- 3 sired times. If desired, a coil spring 34 may be interposed between the head 20 of the spindle 19 and the bottom of the recess 17 of the post 12 to tension and cushion these parts. 7 V

The above is a description. of the mechanical features of my invention, and the operation is as follows: When it is desired to close and lock thegate, the sections 2 and 3 are arranged in a straight line with each other and held by the cleats 1, and the looking board 5 will lie over against the outer face of the sections as shown in Fig. 1. The handle 21 is turned so that the locking block 26 at the end of the spindle 19 will be turned together.

to such position that it will register with and be forced into'the recess 31 by the outward pressure of the bowed spring 24:, and under these conditions the locking head or bar 18 of the post 12 will turn with the latter and lie crosswise of the open-ended slot in the end 7 of the locking board, and bearing against such board will clamp the latter against movement, thus locking the parts- If it is desired to unlock the board, the handle 21 is pulled outward against the action of the bowed spring 24,

thereby depressing the spring or flattening it and withdrawing the locking block 26 from the recess 31. WVhen it has been withdrawn from the-recess, the operator gives ,7 the handlea quarter of a turn, which is permitted because the locking block has been withdrawn from the recess 31 and this causes the locking block to assume a position spanning or extending transversely of the opening 32. of the'plate 33. At the same time this turning movement of the handle will turn the locking head or bar 18 from a I position transverse of the open ended slot to a position longitudinal thereof and thus permit the tail locking board to be withdrawn and the tail board openedor removed.

It is tobe understood that the flanges 22 ofthe bar-like head 20 are made of suflicient depth so that when the locking block 26 is withdrawn from its socket by pulling for? ward or outward on the handle 21, the inner portion of these flanges 22 will still engage in the recessin the head bar 18 so that when the handle is turned, although the block26 is out of its socket, these flanges will still engage with the walls of the slotin the head bar 18 and thus'turn the head bar and its connected parts.

' 7 It willbe noted that I have provided an exceedingly simple, yet efficient form of.

In case it should be desiredto use the. de-' vice on a door, such as a barn door, an addi-. tional handle 35 may be provided'at the end 36 of the shank 19, 'whichin this instance is projected beyond the locking block 26. This handle will lie atthe inside of the door so that the latter may be locked and unlocked from the inside, andunder such conditions it will, of course, be evident that instead of locking block, the handle will be pushed to force such locking block from its locking re- CBSS.

While I have herein shown and described one particular embodiment of my invention,

I wish it to be understoodthat I do not confine myself to, all the precise details-of conpulling on the handleyline to release the struction herein set forth by wayof illustration, as modification and variationmay be made without departing from the spirit of the invention or exceeding the scope of the appended claim. What'I claim is z is .The combination with a wall-and a mem-' her to belocked thereto,of a locking device rotate the latterja'locking block carried at' 7 carried bythe wall comprising a rotatable post having a locking head adapted to fasten the member to be looked, a spindle extending 1 the inner end of the spindle, a keeper for the locking block, means normally forcing the In testimony whereof, I affix my signalocking block of the spindle into looking enture, in the presence of two Witnesses.
